Tensui Saryo is a refined ryokan in Hakone's Miyanoshita district, drawing strongly sulfurous mineral water from one of Hakone's most historically distinguished spring zones — Miyanoshita, where the first Western-style hotel in Japan (the Fujiya Hotel, 1878) was built to accommodate foreign guests of the Meiji-era treaty ports who came to 'take the waters' in the shadow of Mount Fuji. The sulfurous springs — the same type that produce the black eggs (kuro-tamago) of Owakudani's volcanic valley — are deeply therapeutic for skin conditions, rheumatic disorders, and fatigue recovery in an atmosphere of exceptional Japanese hospitality art. The Hakone Open Air Museum, the Pola Museum with its Monet and Picasso collection, and the Hakone Romance Car train gliding through cedar forest toward Mount Fuji's reflection in Lake Ashi surround this refined thermal ryokan with Hakone's unparalleled combination of volcanic art and landscape.

Insider tip — Allow at least 2 hours to fully enjoy the sulfurous waters of Hakone.
